Post-sustainability: the condition of environmental, political, social, and economic systems after the imposition of Communitarianism.The Post Sustainability Institute was established to study the impacts that United Nations Agenda 21/Sustainable Development and Communitarianism have on liberty. Our intent is to track the progression of the Sustainability movement and to forecast the most likely outcomes if it proceeds unchecked.

We are a non-partisan, non-governmental think tank based in the United States. It is our intention to provide a clearing house for information on United Nations' alliances with non-governmental and governmental groups seeking to erect Communitarianism as the dominant form of world governance, and to serve as a rallying point for those who oppose the dismantling of liberty. We welcome your participation and assistance.*****BEHIND THE GREEN MASK: U.N. AGENDA 21, the new book by Rosa Koire, is available now. Please click here to purchase your copy.*****Our partner website: DemocratsAgainstUNAgenda21.comexplains the basics of how UN Agenda 21 has affected Americans in their towns and counties, and describes what methods are being utilized to impose it upon unwitting citizens.

On that site you'll find discussion and links to UN documents, ICLEI, and various non-governmental organizations with policy making and influencing powers, as well as anti-Communitarian sites, the US Constitution, Bill of Rights, and grassroots whistleblower groups.
